Lite Deployment

Authelia can be deployed as a lite setup with minimal external dependencies. The setup is called lite because it reduces the number of components in the architecture to a reverse proxy such as Nginx, Traefik or HAProxy, Authelia and Redis.

This setup assumes you have basic knowledge and understanding of IP addresses, DNS and port forwarding. You should setup the domain you intend to protect with Authelia to point to your external IP address and port forward ports 80 and 443 to the host you plan to host the docker-compose.yml bundle.

Port 80 is utilised by LetsEncrypt for certificate challenges, this will automatically provision up-to-date certificates for your domain(s).

Traefik publishes the respective services with LetsEncrypt provided certificates on port 443. The provided examples protect the Traefik dashboard with Authelia's one-factor auth (traefik.example.com) and two instances of the whoami container with Authelia being bypassed (public.example.com) and another with it's two-factor auth (secure.example.com).

If you happen to already have an external SQL instance (MariaDB, MySQL or Postgres) this setup can easily be adapted to utilise said service.

Steps

  • git clone https://github.com/authelia/authelia.git
  • cd authelia/compose/lite
  • Modify the users_database.yml the default username and password is authelia
  • Modify the configuration.yml and docker-compose.yml with your respective domains and secrets
  • docker-compose up -d

Reverse Proxy

The Lite bundle provides pre-made examples with Traefik2.x, you can swap this out for any of the supported proxies.

FAQ

Can you give more details on why this is not suitable for production environments?

This documentation gives instructions that will make Authelia non resilient to failures and non scalable by preventing you from running multiple instances of the application. This means that Authelia won't be able to distribute the load across multiple servers and it will prevent failover in case of a crash or an hardware issue.
